I've searched, but not really found the answers i'm looking for. I'm in the process of swapping an ls1 into my firebird. Later on down the line i'd like to add a magnacharger to the setup. I know the general consensus are a procharger/turbo/nitrous are better at the track, but i'm just trying to build a fun street car.

Anyway, would i be able to add a maggy to a stock engine and be ok with some good tuning, or do some internals need to be replaced? I don't even need to run very high boost. 7psi would be enough. I could always do a rebuild later if i want more.

No, you would'nt have to change any internals they just replace your intake.

You can add a maggie to your stock setup without changing any internals, but definitely don't go above 7psi. With a maggie on 7psi, headers, good exhaust, and good tuning you could be at 460+rwhp. With heads, cam, bolt-ons, and a good tune, you could easily top 525+rwhp, but it's your ride and $6,600 is a lot to shell out for the maggie alone. You could add to the kit later as time and money allow.

You definitely can bolt a Magnacharger to your stock engine. That's not the route I'd go, but people have done it and I'm sure it's a great street setup. Do a search, there are quite a few threads, vids, and pics here about Maggie's on LS1's.

I know heads and cam would benefit it more than just on a stock engine...but i don't have the money to dump on doing everything at once. Besides, after a point i have to start looking at rear-ends and tranny's and forged parts...so that's even more expense. I just enjoy the low end tq you get from a roots style blower.

for every day street, with fun and reliability being 1st on your list...
you can't beat a maggie.
unless you can fab up a turbo.
